Application clean rs is, near. Manama- The invention relates to a separator and more particularly separators for use e imperfect beans, peas,- ains or seeds can be floated off from the perfect beans, peas, glil'ains or seeds; 1

Another object of t einvention is the proin a plurality of receptacles are nested, one

the perfect and imper ities in a batch can be ed by gravitation and harmless liquid agent feet grades of commo automatically separa such grades of commodities readily and conveniently removed ating operation from the liquid solut on or agent wlthout any1 possibility of ag1tat1on.to the solution whic ,would have a tendency to change the gravity of the same.

A further object of the invention is the provision ofa, .separator of this character,

wherein the construction thereof is novel in form as the units of the device are readily j the necessity of agitation,

grades of commodities being readily extractsepar'able one from the other, to permittheconvenient extraction of the best or better grades of commodities when introduced therein, as the grades of such OOmmOdItiGS will be automatically separated into independent batches, the separation being individual in character in contradistinction to a continuous operation raters, the good positively separated from each'other in the use of the machine or device.

A still further object of the invention is the provision of a separator of this character wherein a batch of commoditiesisintrodu therein, to effect the positive separation of the good and poor grades of commodities from each other, with dispatch and without the separated ed with dispatch and without affecting the liquid agentcontamed within the device, the 7 liquid agent or solution being usable for a maximum len h of time and without liabilit of detenorating effect on the better or =goo grade of commodity separated.

vision of a separator 0f this character, where after the separating oper-' respondin of the well known septa-- and poor commodities being A still further object'of'the invention is the ,provisionof a separator of this character, which is extremely simple in construction, thoroughly reliable and eficient in its purpose, strong, durable, sanitary, and inexpensive to manufacture and operate. 7

.With these and other 0 jects in View, the invention consists in the features of construction, combination and arrangement of parts,-as will be hereinafter more fully described in detail, illustrated in the accompanymg drawings showing the eferred embodiments of the invention, and inted out in the claims hereunto appende It is to be understood, however, that changes, va- "riations and modifications ma. be made in the separator, as come pro rly scope of the a pended claims without depart ng from t e spirit of the, invention or sacrificingany of its advantages;

In the accompanying drawings:

within the Referring to the drawings in detail, the A separator com rises an outer tank A, the same being ma e preferably from sheet metal and of the required size and shape to give maximum capacity thereto. This outer tank A is o ened throughout its top and has an imper orate bottom 10, front and rear walls 11, .and side .walls 12, these walls being of uniform height. Removabl nested within the cuter tank A and suite 1y spaced from the inner faces of the bottom, front, rear and side walls 11 and12, respectively, is an intermediate tank B, which is formed with a wire mesh or perforated bottom 13,- solid front and rear walls 14 and solid side or end walls 15, reipectively. The n per or top of the tank is open-with e uppermost edge horizontally flush withthe'upper edge of the outer tank A. 4

within or nested in the intermediate tank Bis an innermost tank or separa- C is adapted to rest upon the wire mesh or 24, the latter being perforated bottom 13 of the intermediate tank B as is clearly shown in Figure 1 of the drawings. .In the nesting of the outer tank A, intermediate tank B and separator 'body or frame C there will be; resented therebetween liquid spaces 18 an 19 entirely about the intermediate tank B and said body or frame C, while the wire mesh or perforated bottom C of the tank B will constitute a false bottom for the separator body or frame C as will be apparent and in view of the wire mesh character or perforated formation of said body 13, liquid. introduced will flow therethrough into said separator body or frame C as will be obvious.

Arranged in the same horizontal or transverse plane intermediate the open bottom and top of the separator body or frame C is a series of spaced parallel rocking shafts 20, which are spaced an equi-distance apart and are journaled in the front and rear walls 16 of the body or frame C as is shown clearly in Figure 2 of the drawin The front or forward end of each shai t 20 is extended and bent to provide a crank 21 and these cranks of the shafts 20 are pivotally 'connected to a shiftable bar 22, common to all of the cranks for effecting the simultaneous rocking of the shafts 20. Fixed to the shafts 20 are louvers or shutter 23 which are adapted to open and close with relation to each other on the rocking of the shafts 20, so that when the louvers or shutters are in closed position the will shut off the upper portion of the b0 yor frame 0 from the lower portion thereof and on the, opening of the said louvers or shutters the upper portion and lower portion of the body or frame 0 are in direct communication with each other for a purpose presently described.

Swingingly connected to the front wall 16 of the body or frame C is an operating lever supported upon a pivot 25 suitably fastened in said frontwall 16 and is extended upwardly beyond the 0 en top area of the separator, while engage in the bar 22 is a lug 26, the latter being extended into an elongated slot 27 formed'in the lever 24, whereby the latterwill be positively connected with the bar 22,. so that on the swinging of the lever 24 the louvers or shutters 23 can be opened and closed for the purpose presently described. I

In the operatlon or use of the separator hereinbefore described a solution "or liquid agent of alkali, with starch and calcium chloride, the solution being ofBaum test number 40 of three-tenths of one per-cent alkali, is introduced into the said separator,

when the, tanks A, B and body or frame 0 are assembled or nested as heretofore stated, the level of the solution or liquid agent being varied to meet the fancy of the user of the separator. Now, on introducing a commodity, such as beans, peas, grains and seeds through the open upper end of the body or .frame G into the liquld agent or solution, the

'good or perfect grade of commodity will gravitate'onto the bottom 13 of the tank Thereafter the shutters or louvers 23 will be closed, thus shutting off the graded commodit and on the lifting of the body or frame O rom the separator the poor or inferior or im be extract from the machine first, and thereafter the good or perfect grade of commodity confined within the tank-B can then be removed from the machine or separator as will be clearly obvious. On the removal of the body or frame and the tank B the solution or liquid a ent will not become agitated or unduly isturbed to alter the gravity characteristics of such solution or liquidagent. The solution or liquid agent of the Baum, test referred to is harmless in the use thereof for carrying out the method of separation of the commodit or in the operation of the machine herembefore described.

Furthermore it will be apparent that on removal of the tank B an the body or frame C from the outer tank A, the latter can be used continuously for the retention of the solution or liquid agent and this would permit of a'maximum ca acityof the so arator as to theamount o commodity which could be separated and cleaned.

From the foregoing it is thought that the construction and manner of operation of the separator will be clearly" understood, and therefore a more extended explanation has been omitted.

What is claimed is 1. A. separator comprising an open top tank adapted to contain a gravitation solution for grading a commodity, a removable,

open top intermediate tank positioned withbeing sepaer fect grade of commodity can III spaced relation with of the intermediate tank, said inner t'ank having an open top and bottom, a normally inactive combined separating and carrier means within said inner tank above the lower endthereof, and operating means for shifting said separating and carrier means to active position to provide for the latter to perform its separating and carrying function.

2.
